The board of education said it would re-write the criteria in April, giving greater weight to teacher evaluations in deciding the fate of an educator's license.

Tennessee Education Commissioner Kevin Huffman supported the policy adopted in August, but said Friday's adjustment represented an appropriate step as education reforms are tweaked. He also pointed out that since TVAAS results contribute to teacher evaluation scores, they'll still play some role in whether or not an educator is qualified to teach in the state.

The debate over the role of TVAAS testing is still unfolding. Some local districts plan to use the scores to award bonuses, according to the Nashville Tennessean.
